As China Telecom rolls out 4G LTE services nationwide, IPv6 will help the operator manage the anticipated explosion in demand for new IP addresses. Becoming IPv6-ready is a key part of China Telecom’s plans for wider 4G LTE network deployments.

Since April, ZTE engineers have been collaborating with China Telecom to prepare for the IPv6 commercial test, developing test scenarios and solutions. ZTE helped China Telecom overcome complex engineering challenges including the large number of network interfaces and wide network coverage areas, while ensuring existing services on the live 4G LTE network are not disrupted.

This successful IPv6 test fully verified the IPv6/IPv4 dual-stack capabilities of China Telecom’s 4G LTE network in Hunan, laying a solid foundation for the operator’s plans for wider deployment of 4G and other next-generation services in the future.
